Purpose:
To elucidate early and long-term continence and patient comfort depending on type and duration of catheterization after robot-assisted radical prostatectomy.
Methods:
198 patients were randomized prospectively into three groups (May 2016-July 2017): A transurethral catheter with micturition on postoperative day (POD) 5 was placed in the control group (TD5); a suprapubic tube (SPT) with micturition on POD 5 was placed in the group SD5 or with micturition on POD 2 in group SD2, respectively. Questionnaires were used for catheter-related satisfaction. Functional outcome analysis included residual volume analysis, uroflowmetry, IPSS, 12-h pad test, and daily pad use. Follow-up was conducted up to 12 months.
Results:
Postoperative comfort and catheter-related complications were similar in the three groups. However, on the day of catheter removal, continence was significantly better in the 12-h pad test for the SD2 group with 14 ml vs. 30 ml (TD5) and 24 ml (SD5), p = 0.007. Median residual urine volume between the groups was comparable with 17 ml in TD5, 7 ml in SD5, and 11 ml in SD2, (p = 0.07). Postoperative IPSS did not differ significantly in the follow-up period. After 4 weeks, 63% of the patients in SD2 were continent (no pad/day) compared to 33% in TD5 and 41% in SD5, p = 0.004. After 12 months, 76% were continent in TD5, 87% in SD5, and 94% in SD2, p = 0.023.
Conclusions:
Early micturition after SPT placement in robotic radical prostatectomy seems to be beneficial without an increased risk of complications.
